VALVE FOR VAPOR-BURNERS.,

SPECIFICATION forming part of Letters Fatent No. 277,661, dated May l5, 1883,

Application filed August 2l, 1882.

To all whom it may concern:

Be it known that I,DAV1D E. BANGS, of Medford, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Valves for Vapor- Burners, ot' which the following is aiull, clear, and exact description.

This invention has for its objects to provide a novel and efficient valve for vapor-burners, by which the deliver-yet' hydrocarbon can he regulated iniinitesimally, to provide novel -means for holding the rotary dish-valve in close contact with its seat, and to provide novel devices for rotating` the valve-stem and its attached valve. These objects I accomplish by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figurel is a view showing the valves in elevation and in connection with a coil of pipes which lead to a vapor burner or burners, and as adapted to regulate the supply of hydrocarbon to said burners. Fig. 2 is aplan view, on an enlarged scale, ot' the valve and its mechanical connections. Fig. 3 is a vertical section on line 3 3, Fig. 2; and Fig. 4 is a horizontal sec- Fig. 5 is a plan view below line 5 5, Fig. 3.

In the drawings, A represents a coupling adapted at its ends B C to be connected to a pipe for the passage ol' liquid hydrocarbon to a burner for burning its vapors. The coupling A, between its two ends B C, has a chamber, D,which receives the valve-dislt-E, and a chamber, F, which has a passage, a, making communication with one end, B, of the coupling A, and a passage, b, through the thickness of the wall d, which wall makes the seat for the valve-disk E and separates two chambers, D and F. The valve-dish turns within the chamberD,inclose contactwiththevalve-seatforined by the wall d, and it has an opening, j', through its thickness, and in position, by the turning ol' the valve, to be opened and closed for the passage of liquid hydrocarbon through it and The valveopeningj" tapers from end to end in the direction of its turning, and can be set in relation to the opening through the valve-seat for the (No model.)

l delivery of infinitely small quantities ol' hydrocarbon from the chamber F to the pipe connected at end C ot coupling, or by bringing the whole opening/of the valve-disk in line with the opening ofthe valve-seat for the delivery of. the largest amount of hydrocarbon at the end C ot' the coupling. The valve-disk E is attached to a stem, g, arranged to turn within a screw-nut made in two parts, G H, and secured within a screw-threaded socket, L, ot` the coupling A. One part, G, of the screw-nut screws and has a bearing against a shoulder, E, ofthe valve-stem g, and the other part,H, screws and has a bearing against said part G, and by the two the valve-disk is made to have close contact with its seat. The valve-stem g outside ofthe couplinghas an arm, m., which, by a slot, n., antLpivot s, is connected to a lever-handle, M, turning upon a fulcrum, t.. This handle M is for operating the valve E, and it is provided with an arc-shaped slot, N,which receives the projecting end ot the valve-stem g, and is of a length to act at one end as a stop to the opening and at the other end to the. closing of the valve. This connection ofthe lever-handle secures the smallest amount ot' movement to the valve with an extended movement of the lever-handle, enabling the valve to be easily and readily adj usted as to the quantity of the liquid hydrocarbon desired to pass through the pipe to the burner. The valveseat d has a piece of leather, o, upon it for a yielding bearing for the valve-disk, which can be of any other suitable material, or dispensed with; but it is preferable to have it', for the reason stated.

A faucet has heretofore been provided with a horizontal diaphragm having a semicircular opening through it on which diaphragm the valve-plug turns, said plugl having a passage through it of the same shape as the opening through the diaphragm; and in anotherinstance a valve has been provided with a valve-seat having two circular pert'orations through it, a disk-valve being arranged to turn on the valveseat, and provided with two peri'orationsot' the same circular form as those in the seat; but such constructions are not claimed by me, and do not constitute my invention.

2 l Watson Having thus described my invention, what I claim, and desireto secure by Letters Patent, is-

1. In a valve composed of a coupling divided internally into two chambers, D and F, by a partition, d, forming a valve-seat, and having the passage b, the valve-disk E, arranged to turn in contact with the valve-seat, and having the openingf constructed to taper, asshown, in the same direction as. the valve-disk turns in opening the valve, said tapering opening being capable of adjustment over the opening in the valve-seat to provide for the passage ofthe least amount of hydrocarbon iuid, substantially as described.

2. The combination of a coupling,A, having a screw-threaded socket, L, and a wall, d, forming a valve'seat, the valve-stein g, carrying a valve-disk, E, and the screw-nut composed ot' two parts, Gr and H, fitting thc socket in the coupling, and serving to retain the valve-disk in contactvvith its seat, substantially as described.

3. The combination of the valve-stem g, arranged to rotate in its bearings, and having at its inner end an attached valve, E, provided with an opening, and arranged-,to turn in contact with a valve-seat, with a lateral arm, on, connected With the outer end of the valve-stem, and a lever, M, fulcrumed at one end, and loosely connected with the arm of the rotary valve-stem, substantially as described.

4. The combination ot' the valve-stem g, ar-

ranged to rotate in its bearings, and having at its inner end an attached valve, E, provided with an opening, and arranged to turn in contact with a valve-seat, with a lateral arm, m, connected with the outer end ofthe valve-stem, and having a pin, s, and a lever, M, fulcrumed at one end, and having a circular slot, N, into which projects the pin on the lateral arm, substantially as described.

In testimony whereof Iba-ve hereunto set my hand in the presence of two subscribing vvitnesses.
